I’m running Yosemite, and SonicWALL Mobile Connect does not add the VPN’s DNS server to my Mac’s configuration. This appears to be the same problem that komakino_pdx is having. The DNS server is listed on the “Monitor” tab of the interface, I can ping it, and I can even do a manual DNS lookup using that server with nslookup and specifying the server. Otherwise, the server does not appear in /etc/resolv.conf, and no other software can resolve addresses using the VPN’s DNS. For all of its problems, Netextender never had this particular issue. Having upgraded to Yosemite, I can’t use Netextender anymore without installing the old broken Java 6 runtime - no thanks.
